We hesitated to go on this tour, after seeing some of the negative reviews here. But the concierge at our hotel assured us that his guests were always quite thrilled with it, so we went ahead and risked it. (besides, it was considerably cheaper than other tours, and skipped Pisa, which we had been told wasn't worth it) We are so glad we took his advice! This was an absolutely delightful, well-organized day, with a knowledgeable, friendly, upbeat tour guide (Barbara). San Gimignano is breathtaking, and the wine tasting and introduction to all things pertaining to olive oil, balsamic vinegar and wine quite enlightening - and so yummy, we went home with some homemade 8 year old balsamic vinegar. Don't bother with the package lunch they offer (though it's a steal at 10 euros, including wine) and save yourself the walking tour of Siena. But everything else was magical. If we go back to Italy someday, we'll start our trip in Tuscany, thanks to Barbara's introduction.
